“[E]nd users won’t rush to replace their infrastructure with greener technology, says Blair Pleasant, president and principal analyst of research firm Commfusion LLC. For one thing, there are budgets to consider. Pleasant likens the principle to the car industry — many consumers might want to drive expensive hybrids but aren’t ready to replace their perfectly serviceable, gas-powered vehicles.

Plus, there’s some skepticism that environmentally friendly systems might not work as well as familiar, existing networks. Companies “are going to have to prove that the new technologies or systems are every bit as good as what [end users] already have,” Pleasant says.”

Despite the eco-friendly peer pressure, many companies have and will continue to forgo potential long-term savings over increased capital expenditures until the premium to do so diminishes. It will be interesting to see how this plays out as the green movement continues to build steam and as the media continues to barrage us with global warming news. If hybrid vehicles really start to take off, will green data centers too?
